The Rhino Coffee Gear Spinjet Upgrade allows you to easily turn your standard Rhino Coffee Gear spray assembly into a Spinjet option. Simply unscrew the current shower and screw on the Spinjet Valve. The Rhino Coffee Gear Spinjet Upgrade Valve sprays and spins at the same time, creating a more effective and efficient mechanical cleaning action than normal rinsing valves. This design is ideal for plungers, pitchers, and other vessels which are often difficult to clean.
